Bruce Fink

Born in Illinois in 1861, Bruce Fink became one of the best-known American experts on lichens, the complex organisms formed by a partnership of fungi and algae. He studied at the University of Illinois, earned further degrees including work at Harvard and the University of Minnesota, and built a career that combined teaching with careful scientific research.

Fink spent much of his professional life at Miami University in Ohio, where he taught botany and became widely associated with lichen study in the United States. He published important works on North American lichens, including studies of Minnesota species and a major survey of the lichen flora of the United States. His reputation was strong enough that later scientists named the genus Finkia in his honor.

Although remembered mainly as a specialist, his work also helped make botany more accessible to students through university teaching and clear scientific writing. He died in 1927, leaving behind a body of research that remained useful to botanists and lichenologists long after his lifetime.
